These four case studies are interactivities based on actual scientific research projects carried out by leading teams in the field. Each case study takes the participant through a series of steps in a research project — just follow the step-by-step instructions to test a hypothesis or analyze data. The case studies provide an interactive experience that complements the video and text chapters and provides a window into the choices, challenges, compromises, and rewards associated with biological inquiry.
